Alex:
For recent papers on the relationship between "awareness" and
neuronal activity you might want to read
Francis Crick & Christof Koch (1995). Are we aware of neural activity
in primary visual cortex? Nature 375: p. 121-123.
Alan Cowey & Petra Stoerig (1995). Blindsight in monkeys. Nature 373:
p. 247-249.
The latter article is about as close as neuroscience can currently
get in trying to find the neuronal basis for (perceptual) consciousness.
